Completely understandable.
But some people cash out their 401(k), or even purchase large amount of bitcoin inside a 401(k) , or are otherwise independently wealthy, and for such situations it is very difficult, if not impossible, to find KYC-free methods of purchase.
Yeah... In those cases it's going to be hard. On the other hand, nobody prevents you from spamming Robosats and Bisq with $2k buy order at a reasonable premium 😂 You'll have to spend a few days managing all these orders and transferring fiat to many people, but I would say there's no conceptual limitation 😂
Also, afaik, Bisq has no limits for buying/selling Bitcoin (depends on the payment method though), so technically you could buy/sell corn within 0.1-1 BTC (insanely high amounts for me, some people can apparently afford it).
I think going above this level of stacking bears serious risks anyways, regardless of KYC or not. So breaking down the fiat stack and purchasing small portions of corn sounds like a reasonable alternative to me.
